Virtual globes: The web-wide world (google earth) -- Nature [clip]

Describes the huge impact that Google Earth is having on the science. Here's a letter I wrote on this:

I was very impressed with Declan Butler's recent article on the impact that Google Earth is having on the scientific community. I have found this program extremely exciting to use and exhilarating as far as viewing common locations. I would like to point out that the success of this program underscores the importance of open standards for data and having easy interoperation between information resources.
    To some degree, this same success has been achieved in the macromolecular structural world, where there are many programs giving people the ability to easily look at macromolecules in 3D and layer information on them.
    Clearly, a good visualization program and open "browsing" system can catalyze a lot of interesting science. I would like to urge the development of comparable
browsing applications for other newly emerging areas in the biological sciences -- in particular, for visualizing the vast landscape of the genome and for navigating through complex biological networks.

How Do I Love Thee? -- The Atlantic Monthly [clip]

Interesting article talks about the pseudoscience of rigorously determining "Briggs-Myers" personality types and compatibility metrics between people. Personally I think this is more of an art than a science. In anycase, it appears that there will be a vast amount of "social" data mining on the internet in years to come!

emPAI -- MCP [clip]

Useful to refer to in relation to quantifying protein abundance. (Note earlier paper too.)

Mol Cell Proteomics. 2005 Sep;4(9):1265-72.
Exponentially modified protein abundance index (emPAI) for estimation of absolute protein amount in proteomics by the number of sequenced peptides per protein.
Ishihama Y, Oda Y, Tabata T, Sato T, Nagasu T, Rappsilber J, Mann M.
To estimate absolute protein contents in complex mixtures, we previously defined a protein abundance index (PAI) as the number of observed peptides divided by the number of observable peptides per protein (Rappsilber, J., Ryder, U., Lamond, A. I., and Mann, M. (2002) Large-scale proteomic analysis of the human spliceosome. Genome. Res. 12, 1231-1245). Here we report that PAI values obtained at different concentrations of serum albumin show a linear relationship with the logarithm of protein concentration in LC-MS/MS experiments. This was also the case for 46 proteins in a mouse whole cell lysate. For absolute quantitation, PAI was converted to exponentially modified PAI (emPAI), equal to 10PAI minus one, which is proportional to protein content in a protein mixture.....

First of all, how unprofessional, and secondly, it is "reap what you

least spell it right? And WTF is with her "blab la bla"? Does she not
read your e-mail about it being a small community?! So, finally, can I
forward this along to some folks? I am sure they would love to see how

A real lawyer would have put the contract into writing and not exercised

Dianna -

Given that you had two interviews, were offered and accepted the job
(indeed, you had a definite start date), I am surprised that you chose
an e-mail and a 9:30 PM voicemail message to convey this information to
me. It smacks of immaturity and is quite unprofessional. Indeed, I
rely upon your acceptance by ordering stationery and business cards with
your name, reformatting a computer and setting up both internal and
external e-mails for you here at the office. While I do not quarrel
with your reasoning, I am extremely disappointed in the way this played
out. I sincerely wish you the best of luck in your future endeavors.

Dear Attorney Korman,

At this time, I am writing to inform you that I will not be accepting
your offer.

After careful consideration, I have come to the conclusion that the pay
you are offering would neither fulfill me nor support the lifestyle I am
living in light of the work I would be doing for you. I have decided
instead to work for myself, and reap 100% of the benefits that I sew.

Thank you for the interviews.

A Ray of Hope for Diabetics -- Times [clip]

Interesting article about a drug that slows digestion of food (making you feel fuller). It pointed out how doctors might be under pressure to prescribe off-label.

A Ray of Hope for Diabetics
Peter DaSilva for The New York Times
Byetta, a diabetes drug that was approved for marketing last April, has shown strong growth in the number of prescriptions written.
Published: March 2, 2006
The users call the drug Lizzie, the Big Brother or sometimes Gilly. On blogs they rave over its uncanny ability to melt away pounds, although some are wary of its side effects, which can include nausea and strange welts. The users are not fad dieters or methamphetamine addicts, but people with diabetes. And the subject of their rhapsodies is not a gray-market diet pill sold on late-night television but Byetta, a federally approved diabetes medicine, available only by prescription, whose popularity and sales have soared since its introduction last June....

Taking Snooping Further; Government Looks at Ways To Mine Databases -- Times [clip]

Thought this was an interesting article about the practical value of data mining. It seems that of the big applications of mining -- e.g. genomics, credit-card fraud, marketing, anti-terrorism -- mine is the only one that's open and not shrouded in secrecy...

Taking Snooping Further; Government Looks at Ways To Mine Databases
Published: February 25, 2006
PALO ALTO, Calif., Feb. 23 - A small group of National Security Agency officials slipped into Silicon Valley on one of the agency's periodic technology shopping expeditions this month.On the wish list, according to several venture capitalists who met with the officials, were an array of technologies that underlie the fierce debate over the Bush administration's anti-terrorist eavesdropping program: computerized systems that reveal connections between seemingly innocuous and unrelated pieces of information.The tools they were looking for are new, but their application would fall under the well-established practice of data mining: using mathematical and statistical techniques to scan for hidden relationships in streams of digital data or large databases.Supercomputer companies looking for commercial markets have used the practice for decades. Now intelligence agencies, hardly newcomers to data mining, are using new technologies to take the practice to another level...
